The songs been taken from a live musical with humans and puppets called Avenue Q, some of it with the REAL Gary Coleman! (who is the Gary in question when katie monster sez ' and you keep selling your stuff on e-bay' )
Here is a video of the real thing, not as funny, but if you listen to some of the lyrics the person acting as Gary says, kinda funny, as he takes the piss out of his earlier years and being ripped off by his own folks...
